Benefits of technology
The present invention relates to a wearable device that can monitor the autonomic nervous system (ANS) by measuring blood flow data and motion data. The device includes a photoplethysmography (PPG) sensor and a motion sensor, which can capture blood flow data when the user is in a stationary position or performing spontaneous respiration. The device can also determine the autonomic dysfunction by analyzing the time-interval data and the parasympathetic index values. The device can provide haptic feedback to the user and control the actuator based on the autonomic nervous system condition. The technical effects of the invention include improved monitoring of ANS activity and wellness monitoring.
Problems solved by technology
This is because more strenuous physical activity causes heart rate to increase, which can distort heartbeat measurements used in evaluating ANS conditions or health, and because ANS analysis may be unreliable without a sufficient large data set.
Such a requirement inconveniences users, resulting in lower of participation, and degraded user health over time.

Embodiment Construction
[0038]Various embodiments will now be described more fully with reference to the accompanying drawings, in which some, but not all embodiments of the disclosure are shown. This disclosure may be embodied in many different forms and should not be construed as limited to the embodiments set forth; rather, these example embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the disclosure to those skilled in the art. Like numbers refer to like elements throughout.
[0039]FIG. 1 shows an example computing system 100, in accordance with some embodiments. A user may access a health monitoring service provided by a central system 102 via a network 112 (e.g., the Internet) using a user device 108 and / or a wearable device 110. Moreover, the central system 102 may comprise a server 104 and a database 106. Although a single user device 108 and wearable device 110 is shown in FIG. 1, the system 100 may include multiple user devices 108 a...

Techniques are disclosed for generating user information from autonomic nervous system (ANS) parameters and continuous ANS monitoring. Some embodiments may provide a wearable device, comprising: a photoplethysmography (PPG) sensor; a motion sensor; and processing circuitry configured to: determine one or more monitoring conditions; determine whether the one or more monitoring conditions are satisfied based on monitoring motion data from the motion sensor; capture the blood flow data with the PPG sensor when the one or more monitoring conditions are satisfied; determine time-interval data indicating times between pulses based on the blood flow data; determine an ANS condition based on the time-interval data. The blood flow data and / or time-interval data may be captured and aggregated from multiple discontinuous periods of time when monitoring conditions are satisfied. The processing circuitry may be further configured to control output devices for presentation of the ANS condition(s), such as an actuator of the wearable device.
Description
CROSS-REFERENCE TO RELATED APPLICATIONS[0001]The present application claims the benefit of U.S. Provisional Patent Application No. 62 / 067,955, titled “Generating User Information from Autonomic Nervous System Parameters,” filed Oct. 23, 2014, which is incorporated herein by reference in its entirety.[0002]The present application is related to U.S. Pat. No. 7,092,849, which is incorporated herein by reference in its entirety.TECHNICAL FIELD[0003]The example embodiments of the present invention generally relate to techniques for autonomic nervous system (ANS) monitoring.BACKGROUND[0004]Evaluating the ANS health of a user conventionally requires that the user remain substantially stationary, or in a supine or quasi-supine position. This is because more strenuous physical activity causes heart rate to increase, which can distort heartbeat measurements used in evaluating ANS conditions or health, and because ANS analysis may be unreliable without a sufficient large data set. As such, con...
